The inside of your iron needs cleaning. Unplug it, and when cool, empty it completely. Pour in a half 'n half vinegar and water solution. Pug iron in and steam (don't iron anything!) Hold it over the sink and check the water coming out. Repeat this process until the water is clear. Rinse with clean water until there is no smell of vinegar. There are also commercial iron cleaners available at WalMart, etc.
